STS-51-F, Space Shuttle Challenger Launch, 1985


Challenger jumps off the launch pad in 1985 to begin a successful mission. The main purpose of this mission was to test a new space based laboratory named Spacelab 2. Spacelab 2 takes advantage of the effectively weightless conditions in orbit to carry out experiments in areas such as astronomy, physics, life science, materials science, and atmospheric physics. STS-51-F (also known as Spacelab 2) was the nineteenth flight of NASA's Space Shuttle program, and the eighth flight of Space Shuttle Challenger. It launched from Kennedy Space Center, Florida, on July 29, 1985, and landed just under eight days later on August 6. While STS-51-F's primary payload was the Spacelab 2 laboratory module, the payload which received the most publicity was the Carbonated Beverage Dispenser Evaluation, which was an experiment in which both Coca-Cola and Pepsi tried to make their carbonated drinks available to astronauts. During launch the Challenger experienced multiple sensor failings in its SSMEs and had to perform an "Abort to Orbit" (ATO) emergency procedure. It is the only mission to have carried out an abort after launching. As a result of the ATO, the mission was carried out at a slightly lower orbital altitude.
